Specification of Letters Patent.

Patented Feb. 2, 1909.

Application filed November 9,1905. Serial No. 286,561.

To all whom it may concern:

Be it known that we, JOHN G. STITES and FRANK G. YATES, citizens of the United States, residing in Evansville, in the county of Vanderburg, in the State of Indiana, have invented a new and useful Improvement in a Chart, of which the following is a specification.

Our invention relates to charts and more especially to charts or guide maps of cities in which difierent sections are plotted and shown u on a pluralit of sheets adapted to be bound into pocket ook form.

It is common to secure a map within covers, the map or chart bein folded when held between the covers an unfolded and spread open when in use. A chart of this kind is inconvenient to handle unless the party using the same has a convenient lace upon which to s read out the unfolded 0 art,

and constant f0 ding andunfoldin cause the chart to tear along the line of fol ing. It is also common to plot various sections of a district and bind the said sections in one cover,-

but this separates the various sections and renders the chart less readily read than a continuous chart upon onesheet of paper. v

The object of our invention is to overcome the disadvantages of both of these constructions and to retain the advantages found in both.

Our invention consists of a plurality of charts bound in book form and following each other in such a successive order that when the book is open the separate sections of the district plotted will be shown and the continuation of said districts will also be shown by folding over either of the charts so A that it will lap over upon the marginal portion of the other, the reverseside of each chart forming a continuation of the district:

plotted upon the face side of theother.

In these drawings :Figure 1 represents apages therein and book having a plurality 0 bearing upon each page a map-of a certain portion of a city, thebook being shown open;

Fig. 2 shows the book'open and the righthand page folded longitudinally so that its right-hand margin overlaps and rests upon the right-hand margin of the page upon the left-hand side. Fi 3 is a transverse section through the book sIlown in Fig. 2.

In these drawings, A represents a age bearing a chart showing a certain limite district of a city. This chart extends to the left-hand side of the age A, but amarginal spdace A is left upon tlffe right-hand or bound s1 e. 1

B represents the opposing age having a certain portion of same city p otted thereon, the chart extending to the free edge of the age and a margin being left adjacent the bound edge. To secure the continuation of either of the districts shown u on these pages, it is only necessary to fol the page ongitudinally so that its free edge will overla themargin u on the other age.

In Fig. 2 page is shown fol ed longitudinally its free edge B being blocked in alinement with the chart shown upon page A, and the page B which is the reverse of page B, carries a chart which alines with and forms a continuation of the district chart upon page over, it would show the district lying upon .the right-hand side of the district shown on page A. In order to more readily grasp the relation of these two districts to each other and the manner in which they form a continuation of each other, it is only necessary to bring the free edge portion of page B into alinement with the marginal portion of page A, and page A and the folded over portion of page B will be found to make a continuous chart.

It will be obvious that all of the pages charted are arranged with reference to each other so that the reverse of one page forms a continuation of the face of its opposing page. Having thus fully described our invention, what we claim and desire to secure by Letters-Patent, is p A chart consisting of a plurality of sheets bound together and having contiguous sections of country map ed u on alternate pages, each sheet whenlolded ongitudinally upon itself forming a continuation of the -map printed upon an adjacent sheet.
